Serological Testing for Mycobacterial Heat Shock Protein Antibody in Health and Diseases.

Mycobacterial heat shock protein 65 gene () has been widely used for classification of Mycobacterial species, and detection of Mycobacterial genes by molecular methods and has proven useful in identification of Mycobacterial infection in various clinical conditions. Circulating antibody against Mycobacterial has been found in many clinical diseases including autoimmune diseases (Crohn's disease, lupus erythematosus, multiple sclerosis, diabetes, etc.), atherosclerosis and cancers.

Anti-microbial Antibodies, Host Immunity, and Autoimmune Disease.

Autoimmune diseases are a spectrum of clinical inflammatory syndromes with circulating autoantibodies. Autoimmune diseases affect millions of patients worldwide with enormous costs to patients and society. The diagnosis of autoimmune diseases relies on the presence of autoantibodies and the treatment strategy is to suppress the immune system using specific or non-specific immunosuppressive agents.

Mycobacterium avium subspecies hominissuis in Crohn's disease: a case report.

We have cultured Mycobacteria avium subspecies hominissuis (MAH) from the blood of a patient with Crohn's disease. The patient is a 21 year-old-female with a diagnosis of Crohn's disease for two years. She had been treated with corticosteroids and Humira for six months.

Assessment of two methods for handling blood in collection tubes with RNA stabilizing agent for surveillance of gene expression profiles with high density microarrays.

Genome-wide expression studies of human blood samples in the context of epidemiologic surveillance are confronted by numerous challenges-one of the foremost being the capability to produce reliable detection of transcript levels. This led us to consider the Paxgene Blood RNA System, which consists of a stabilizing additive in an evacuated blood collection tube (PAX tube) and a sample processing kit (PAX kit). The PAX tube contains a solution that inhibits RNA degradation and gene induction as blood is drawn into the tube.
